Subject: utils: media-ctl: Support changed routing API Author: Sakari Ailus <sakari.ai...@linux.intel.com> Date: Wed Apr 24 18:22:25 2024 +0300 Set len_routes of struct v4l2_subdev_routing. ENOSPC error code is no longer used, i.e. having room for fewer routes than exist in the configuration is not considered an error anymore.
